307 Stroker Anyone???
I want to add some grunt to my lil 307. I know I'm gonna catch hell for wanting to keep the same engine instead of swapping to some other engine, but that's what's gonna happen.
I want to add a 3.75" stroke crank from Summit and the 400 SBC 5.565" rods. This will make it a 360 (359) cubic inch. The only problem is the available pistons will be .070 out of the hole. I can get thicker head gaskets or mill my pistons. Ready......GO!!! |

I like different I say go for it

Re: 307 Stroker Anyone???
Do it. Worst case you might have to get some custom pistons made. Have you figured out the static compression ratio? This one from Diamond pistons is my favorite. I've built several Pontiac strokers over the years. Figuring out all the details is enjoyable for me.

Sounds like Fun.:burnout:
The (self proclaimed) Engine Guru's are going to have something to say about this. ;) |
Re: 307 Stroker Anyone???
I'm just curious what the benefit will be.

Nothing wrong with hot rodding a overlooked engine like that since its still SBC and parts availability is huge (other than the odd bore piston deal) more cu.in with small bore should pair well with mild cam for low end torque, only thing you would be giving up over a larger bore like a 350 would be airflow around valves but that is mainly higher rpm problem anyhow.

I just talked with a tech guy at Silv-O-Lite pistons and he said my .030 over pistons are .482 thick at the top. That's PLENTY to take .070 off.
My next call was to the machine shop. They can mill all 8 for about $150. My buddy owns a shop and he had a set of 5.5656" 400 rods I picked up. The 307 (360) stroker is GONNA HAPPEN!!! |

Is a Dyno test in the plans (that's if you have a source close to you) ?

For pistons use Summit racing search engine.
If you know the bore you want to one that is feasible. You maybe able to get a piston with a different compression height to work that is commonly available. |
